Interactions between polyethylene and polypropylene microplastics and Spirulina sp. microalgae in aquatic systems

H. Hadiyanto et al.

Summary: This study found that the growth rate of Spirulina sp significantly decreased under treatment with microplastics (PE and PP), resulting in lower phycocyanin yield and protein content. Scanning electron microscopy and Fourier transform infrared spectroscopy analysis revealed surface damage to Spirulina sp cells and loss of carboxyl groups from proteins in Spirulina sp due to PE and PP treatment.

Single and combined effects of microplastics and lead on the freshwater algae Microcystis aeruginosa

Shan Wang et al.

Summary: The study investigated the single and combined effects of microplastics (MPs) and lead (Pb) on freshwater algal Microcystis aeruginosa. Results showed that Pb promoted algal cell growth, while MPs inhibited growth. Combination of MPs and Pb had a synergistic effect on promoting aggregations of M. aeruginosa. These findings suggest that the interaction of MPs and Pb can have significant impacts on aquatic ecosystems.

Growth inhibition, toxin production and oxidative stress caused by three microplastics in Microcystis aeruginosa

Xiaowei Zheng et al.

Summary: The study revealed that PVC, PS, and PE microplastics had significant inhibitory effects on the growth of Microcystis aeruginosa, impacting its antioxidant enzyme activities, cell membrane integrity, and toxin production. Different types of microplastics had varying degrees of impact on the freshwater algae, with PE microplastics showing the highest resistance.

Size-dependent toxic effects of polystyrene microplastic exposure on Microcystis aeruginosa growth and microcystin production

Di Wu et al.

Summary: The study reveals that 1 μm polystyrene microplastics have a greater impact on freshwater cyanobacteria compared to 100 nm microplastics, promoting algal growth and inhibiting photosynthesis. Additionally, 1 μm microplastics increase intracellular microcystins content and inhibit their release, while 100 nm microplastics only promote microcystin production.

Size-dependent chronic toxicity of fragmented polyethylene microplastics to Daphnia magna

Dahee An et al.

Summary: The chronic toxicity of fragmented microplastics (MPs) on Daphnia magna was higher compared to MP beads, leading to reduced feeding, survival rate, body length, and offspring in the exposed organisms. Further studies are needed to understand the underlying toxicity mechanisms and potential ecological risks posed by MP fragmentation.

Effect of microplastics on aquatic biota: A hormetic perspective

Tao Sun et al.

Summary: The study found that microplastics can enhance biological performance and reduce oxidative stress biomarkers in aquatic organisms at environmentally relevant concentrations. The responses varied among different biological endpoints, with stimulatory effects observed in consumption, growth, reproduction, and survival. The meta-regression analysis showed that the responses to MPs were independent of habitat, MP characteristics, and exposure duration. The findings suggest that exposure to MPs at low and high concentrations may lead to opposite or non-monotonic responses in aquatic biota.

Freshwater alga Raphidocelis subcapitata undergoes metabolomic changes in response to electrostatic adhesion by micrometer-sized nylon 6 particles

Satomi Mizukami-Murata et al.

Summary: The study found that powdered nylon 6 (Ny6-P) significantly inhibited the growth of microalgae, possibly by disrupting cell growth and photosynthetic activity through electrostatic interactions. Metabolomic analysis revealed that induced metabolites might trigger responses in microalgae to cope with starvation and oxidative stress.

Studying microplastics: Lessons from evaluated literature on animal model organisms and experimental approaches

Marko D. Prokic et al.

Summary: The review analyzes the current status of studies on the exposure/effects of microplastics on animals, providing basic knowledge about model organisms and experimental methods, and suggesting future research directions. Data from 500 studies published from January 2011 to May 2020 were summarized, discussing various aspects of model organisms and experimental designs, while also encouraging further investigation of less studied organisms and different aspects of microplastic pollution.

Summary: Plastic pollution is a global environmental issue and research shows that different plastics have varying effects on the growth of freshwater microalgae, being influenced by both concentration and particle size. Among the tested plastics, PVC had the greatest impact, while PP was mostly affected by concentration.

Uptake of Microplastics by a Tropical Freshwater Cladocera Revealed by Polyethylene Terephthalate Fluorescence

Samira G. M. Portugal et al.

Summary: This study found that small-sized tropical freshwater microcrustaceans ingest PET microplastics, with some individuals attempting to egest these particles unsuccessfully, contributing to decreased survival rates. The potential ecological consequences of such PET microplastics ingestion on tropical aquatic food webs are highlighted.

Understanding nanoplastic toxicity and their interaction with engineered cationic nanopolymers in microalgae by physiological and proteomic approaches

Miguel Tamayo-Belda et al.

Summary: The study suggests that nanosize plastics in aquatic ecosystems are difficult to identify and remove, and their toxic effects can be alleviated through combined exposure with other nanomaterials. Additionally, molecular biomarkers can be used to predict cellular damage caused by exposure to nanopolymers and other materials.

Environmental fate and impacts of microplastics in aquatic ecosystems: a review

Sen Du et al.

Summary: The widespread use of plastic products has led to the global presence of microplastics (MPs) in aquatic environments, affecting the health of organisms. Studies have shown that most MPs in water environments ultimately break down into small fragments and sink to the ocean floor. The article also discusses the impact of MPs as carriers of organic pollutants and microorganisms on aquatic organisms.
